APPARATUS FOR MAKING TIE-PLATES.

Specification of Letters Patent.

Patented Aug. 23, 1910.

Application filed November 12, 1908. Serial No. 462,299.

To all whom it may concern:

Be it known that I, VILLIAM GOLDIE, Jr., a resident of Bay City, in thecounty of Bay and State of Michigan, have invented a new and usefulImprovement in Apparatus for Making TiePlates; and I do hereby declarethe following to be a full, clear, and

exact description thereof.

My invention relates to the manufacture of tie plates, its object beingto provide apparatus which will produce a plate having claws on itslower surface in a cheap and easy manner.

It is especially adapted to make plates of a nature described in anapplication for Letters Patent filed by me, Serial No. 404,933, and bythe method described in application filed by me, Serial No. 404,932.

To these ends my invention consists, generally stated, in an anvil diehaving a groove formed therein to receive the claws, and a reciprocatingriveting die above the same to rivet the claws as the plate passeslongitudinally over the anvil die.

It also consist-s in certain other improvements hereinafter described.

In the accompanying drawings Figure 1 is a perspective view of acomplete tie plate of the nature to manufacture which my invention isprimarily intended; Fig. 2 is a perspective view showing the bar fromwhich the claws are formed; Fig. 3 is a view partly in section showingthe apparatus for sharpening the claws cut from the bars of Fig. 2; Fig.4 shows a finished claw; Fig. 5 is a sectional view showing the rivetingmechanism with the riveting die raised; Fig. 6 is a like view with theriveting die lowered; Fig. 7 is a longitudinal section on the line 77,Fig. 5; and Figs. 8 and 9 illustrate modifications of the die to be usedwhere a difierent form of claw is desired.

My invention is devised especially to manufacture claw tie plates of thekind shown andcovered by said application Serial No. 404,933. It is notspecifically limited to their production, however, as it covers all usesto which it may be put. These tie plates have the main body portion 1with the shoulders 2, spike holes 3 and the claws 4, which claws, asillustrated, are formed separate and secured within slots 5 formed inthe body of the tie plate by riveting the claws and plate together, suchplates being described in detail in my said applica tion. The bodyportion of these claw plates are formed by suitable rolling, shearingand punching operations which form no part of my present invention. Theclaws 4 are first sheared from the clawbar 6, as illustrated in Fig. 2.These claws have the head portion 7, the relatively thick body portion 8of a depth slightly greater than the thickness of the plate, and thethinner claw portion 9. The claws have V-shaped points with the inclinedfaces 11. To produce this sharpened claw from the form sheared fromtheclaw bar I provide the apparatus illustrated in F ig. 3. This comprisesthe inclined anvil die 12 having the shearing edges 13 and thereciprocating riveting die 14 with the V- shaped shearing recess 15..This apparatus when operated shears obliquely through the claw blankshown in Fig. 4, and forms the point 10 and inclined faces 11 of thefinished claw. The body portion 8 of the claw is left deeper than thethickness of the body portion 1 of the tie plate. The apparatusillustrated in Figs. 5 to 9, forming the subject matter of thisapplication, is designed to rivet such claws firmly and securely intothe tie plate. It consists in the anvil die 16 having the grooves 17therein. These grooves extend the full width of the anvil die, as shownin Fig. 7, so that the tie plates may be fed along such die and ejectedtherefrom after the riveting operation. The grooves 17 are slightlydeeper than the claw portions 9 of the claws and have the shoulderportions 18 fitting closely against the shoulders 23 on the claws formedby the extension of the head portion 7 of the claws below the bottom ofthe plate when inserted. in the slots 5 therein. As illustrated, theanvil die has also the longitudinal depressions 19 which serve toreceive the shallow flanges 20 which extend across this tie plateinclosing the slots 5 therein. The reciprocating die 21 is provided withlongitudinal recesses 22 corresponding in shape to the heads 7 of theclaws. This riveting head has a stroke adapted to force down the clawsand upset the shoulders 23 of the claw body by means of its shoulder 18at the top of the groove 17 and so secure the claws rigidly to theplates. As illustrated in Fig. 7 it will be seen that the anvil die 16is of much greater width than the riveting head 21, and so constructedas to support several plates for riveting. After the insertion of theclaws in the tie plates the plates carrying the same may be fedlongitudinally under the reciption of the tie plate may be upon theanvil and the plates being simply pushed ofi' the anvil at the oppositeend, dropping off the machine in finished condition.

Substantially the same riveting means may be employed, no matter whatmay be the shape of the claw-or the character of the riveting. Forexample, in Figs. 8 and 9, the claw 24 is provided with side recesses 25formed in its thick body portion; and to hold it in place the loweredges of the slots 26 through which the claw projects can, by a likeriveting means, such as by the ribs 27 formed on the top face of theanvil 28 on each side and above the groove 29 receiving the prongedportion of the claw, by the stroke of the reciprocating head 30 beforced into said recesses and so rivet the claws in their slots.

This apparatus is simple and inexpensive in construction and effectivein operation, as by the use of suitable feeding means the tie plates maybe fed continuously thereto with the claws loosely inserted in the slotsand taken therefrom in finished condition at the other end of the anvil.The waste of metal which has heretofore occurred where claws were formedfrom integral flanges rolled on the bar and then sheared out is entirelyobviated. Besides, longer claws may be employed and they may be locatedin any part of the plate and at any stagger on the plate, and with theirinclined faces in either direction, which was impossible under the oldmethod because the sharpening could not be done unless the claws werelocated very close to the edge and could only be done inwardly.

What I claim is:

1. In apparatus for forming claw tie plates, the combination of an anvildie, and a reciprocating riveting die, one of said dies having a grooveformed therein to receive the claw, said groove having a rivetingshoulder at its outer end.

2. In apparatus for forming claw tie plates, the combination of an anvildiehaving a groove extending across the same and a reciprocatingriveting die above the same, said reciprocating die having a headingreccss extending across in its lower face.

3. In apparatus for forming claw tie plates, the combination of an anvildie having a groove extending across its face to receive the claw, and areciprocating riveting die above the same, the anvil die being made ofgreater width than the width of the reciprocating die to provide for thelongitudinal feed of the tie plates along the anvil die and under thereciprocating die.

In testimony whereof, I the said IVILLIAM GoLDin, Jr., have hereunto setmy hand.
